Angle grinders...

[Clunk]

That reminds me, I must get a visor....... got goggles and glasses but will be no good if me grinder kicks

A clogged disk equals an uneven disk and when spinning at very high rpm equals boom. Should always inspect the disk. If some clown before you has clogged it for the next person, chuck it.

Caught a cock head on site (lucky for him) had a cut quick blade (14") worn down and was attempting to put it in a 7". Quick cut blades are rated for 4400rpm 7" grinder 8600rpm. No visor nadda it would have blown apart at 8600 rpm would have been nasty.


Have a google of Angle grinder injuries PHARKN NASTY!!

Heres a ripper for you true story, Italian guy up the airport doing home renos and was cutting in some door architraves.
Saw wouldn't fit so he removed the saw blade and fitted it to the 9" grinder. Turned it on and lined it up for a cut ,,,,,,,,,,,,,,,
as soon as it touched the timber it bit took off and ended up embedded in his shoulder blade, nasty as you say.
He went to Emergency with saw in his back, very lucky person an idiot but lucky.

Hi John,

Wha did you need explaining?

When using a 9" angle grinder I am a big fan of being in the standing position with both hands on the machine in the operation grip, elbows in and braced to you body, one foot slightly forward like you are ready for a fight. Good balance, a firm grip and respect for the unit will see the job done safely.

As I See it the problem with standing on the unit is when your trying to the lift the bloody thing into an operating positionwhile it's spinning. Nasty bit of kit.

I remember sitting at the Christmas table about 10 years ago while my then 15 year old nephew told me how he and his mate were doing a heap of work on cars and his mates dad let them use his 9" angle grinder in-supervised and how his mates Dad had removed the guard cause it was in the way! I hit the farking roof at the Christmas table!!

He is my nephew by marriage and my wife is the youngest of 4 girls and this young fella did not have a dad so no male figure. I am that guy now. My sister inlaw's all just looked at me. No idea. Needless to say he never used the grinder again. His friends Dad should be bloody shot!! D1ckhead! Right there!

Thanks for the post. Good male mentors is what's wrong with our society.....not enough that care.

best one I saw was a bloke put a 14 inch tungsten blade in a quick cut for cutting old sleepers he didn't run out of luck that time but im sure he would have sooner or later

[kevin07]

The 9inch is a monster of a tool. I can see why they have been banned.

I wonder how the old 12 inch grinders are going at the hire company I worked for an extremely popular item.

A general rule for cutting aluminum is to treat it as wood instead of metal and use wood tools like a toothed blade on a drop saw as mudrunner said.
A mate pushed his alloy bullbar onto his wheel when his 4x4 hit a tree and used a chainsaw to cut it off. Natural reaction from people was that it's a crazy idea but it works better and safer than a grinder with surprisingly little wear on the chain.

[threedogs]

Can see that working as it would be throwing pieces of alloy out and not clogging the blade.
Good out come in an emergency situation, Blades are what $30 each,

Yeah the chain really didnt wear that much at all. A sharpen up and it was as good as new. Probably about the same as 3 loads of wood worth of wear
